IMPROVEMENT IN (LIDER-MILLS.

Specification forming part of Letters Patent No. 44,408, dated September 217, 1864.

To all :rhum t 'muy concern:

Be it known that I, PERRY DicKsoN, of

.Erie, in county of Erie and State of Pennsylvania, have invented a new and Improved Machine for grinding apples and vegetables or roots; and I do hereby declare that. the t'ol lowing 1s afnll, clear, and exact description thereof', which will enable those skilled in the arr to make and use the same. reference being had to the accompanyingdrawings, formii g pant ofthe specitication, in which- Figure l is a side sectional view of my invention, taken in the line a: a', Fig. 2; Fig. 2. a plan or top View ofthe same; Fig. 3, an en` larged View of a portion of the grinding-cylinder.

Similar letters of reference indicate correspondinnl parts.

This invention relates to an improvement 011 what is generally known as the grater mill,7 for grinding' apples for the manufacture of cider, said mill beingl also applicable to the grinding of other vegetables or roots.

This grater mill consists of a cylinder pro vided with aseries ofteeth at its periphery, for grating, cutting, or rasping the apples or vegetables, and the cylinder in a short time after the commencement of its work is liable to become choked, cloggt d, or gummed up, as there is no escape for the particles of cut apples or vegetables from the cylinder.

The object ot' my invention is to obviate this difculty; and it consists in constructing the g1 indin g-cylinder of sheet metal perforated in such a manner as to form teeth and open-v ings for the cut particles of apples or vegeta-- bles to pass Within the cylinder, and thereby admit of the cylinder being kept perfectly clean, so that it will operate perfectly.

A represents a framing, which may be constructed in any proper manner to support the working parts, and B is a hopper, which is placed on said framing, and in one side of which the gratter-cylinder operates or works, as shown clearly in Fig. 1. This cylinder C is constructed lof sheet metal, closed at one end by a circular head7 a., and open at the op posite end, and is fitted on ashaft, D, the bearings of which are on the framing A.

The cylinder (l is perforated with holes, the punch being driven through the sheet metal from the inner side of the cylinder, so as to make a clean cut at one side and form a gougeshape projection or tooth, b, with an opening, c. gradually widening from its outer to its inner end, so as to admit ofthe particles cut by the teeth b escaping freely through the openings c into the cylinder.

The lower part of the interior of the hopper B is of curved form, and gradually diminishes in Width from its upper to its lower end, as shown at d, to torni a throat to admit of the cylinder C acting efficiently upon the apples or vegetables. (See Fig. l.) I

D is a scraper, which is attached to the framing A and projects within the cylinder C. This scraper is of spiral form, and is designed for discharging the ground apples or vegetables from the interior of the cylinder.

The cylinder() may be rotated by gears l from a driving-shaft, E. The apples or vegetables are placed in the hopper B, and they pass down into the narrow part or throat d, and are acted upon by the cylinder (l, the cut particles passing through the openings c into the cylinder U, from which they are scraped and discharged by the scraper D.

Thus by this simple arrangement l obtain a grater-mill which will operate perfectly or eiciently at all periods while at Work, as the cylinder cannot be gummed up with the cut apples or vegetables, but will be kept clean at all times.

I claim as new and desire to secure by Letters Patent- The combination of the cylinder, having teeth made by punching holes from the inside, in combination with the spiral or obliq ue scraper for removing the pomace that passes through the perforations, substantially as de scribed and represented.
